I To all whom tmay concern:

Be it known that I, CLARENCE W. SPICER,

' a. citizen of the United States, residing at A'to whichY it appertainsto make and use the same.

My invention relates to improvements in inca-sed universal joints and inthe casings of such joints, and comprises a casingparticularlyapplicable to the class of universal joints comprising anintermedi-ate member and driving and drivenmembers one o which ispivotally connected to said intervmediate memberand the other of whichhas a sliding connection with said intermediate member. Joints of theso-called T-head in a slot?" type. are ofthe class referred to.

Such jointsare com monly used .in the driving mechanism ofcertain-well-known mo-l tor vehicles, and are 'also adapted for use inboats and in machinery generally wherever a universal joint isrequired.My improved casing is so constructed as to inclose such joints,excluding dirt, dust, and the like from the working parts thereof, andwhen so desired'serving alsoy as a reservoir to contain lubricant bywhich the wearing surfaces ofthe joint Vare kept lubricated at alltimes.

My invention consists in the novel construction of the' casing, and inthe combination of -a casing such as describedk with joints of the classdescribed, and in other features of invention hereinafterdescribed andparticularly pointed out in the claims.

The objects of invention are, to in- I'close in an improved mannerjoints of the class described; 'to prevent dirt', dust and the like.from reaching the wearing surfaces of such joints; to retain .lubricant1n such joints;`and to make the easing simple, compact, neat inappearance, and relatively 1nexpensive.

I will now roceed to describe my inven- Vtion with re erence to theaccompanying drawings, in which one type of said joint' and certaintypes of casings therefor embodying my invention are lllustrated, and

- will then point out the novel features in claims.

Inthe said drawings: Figure 1 shows a central longitudinal section ofa/universal joint anda casing therefor embodying my invention. Fig. 2showsa "transverse sec'- tion of such joint ontheline A-A of" Fig. l.Fig. 3 shows a longitudinal section of said jointand casing on a planeat right angles to that of Fig. l. Fig. 4 is a longi-4 tudinal sectionalview illustrating an alternative forlnof such casing; and Figs. 5 and 6are further detaihlongitudinal sectional views illustrating furtheralternative constructions of such casing. Fig. 7 shows a centrallongitudinal section of st-ill another incased'universal joint having afiat -end plate, and Fig. 8 is an end View of `such joint.

Referring now to the drawings, and at first to Figs. 1, 2 and 3Athereof, l designates the said intermediate member of the .l

universal joint, and 2 'and' 3 end members thereof, of which either maybe the driving member and the otherthe driven member. y

In the construct-ion shown, member 2 is a block of generally cylindricalouter contour,

-having Ain it a transverse slot or slide-way 4, in which vtheintermediate member 1 is adapted to slide, said block being surroundedby a cylindrical jacket 5 4serving to confine the sliding intermediatemember 1 -against lateral escape Yfrom said slide-way.

This jacket 5 has at oneend a'lip 6 which coacts with thespherically-curved casing member 7 hereinafter mentioned.

The member 3 of the joint is pivoted on a trunnion -pin 8 `ofintermediate member 1.

. Upon said member 3 is mounted said .casing ,member 7, 'which is a"spherically-curve shell, embracing the said lip 6 of jacket 5,

and haviga neck-portion 9 in which is an j aperture 10 through which'themember 3 of the joint passes. Casing member 7 ,is further rovided withpacking material 11 just outsi e this aperture 1'0 and surrounding thejoint member 3 and held in plaee by a cap 12.v A spring 13 surroundingsaid `joint member 3 and abutting at 'its rear end against a pin 14,tends I ber 7. against the lip 6 at-the end of ,joint member 2. It willbe s een that the relative relation of jacket 5 and the end nieniber 7of the casing 1s that the-movements to press. casing mem-'.-

of joint member 3 with respect to the other members of the joint. theend member 7 moves back and forth over the end of the jacket, beingpressed against the end 4of the jacket at all times, however, and sokeeping the casing closed. To aid in forming a tight joint between endmember 7 and lip 6, I customarily provide packing material 15 betweensaid members. Such packing material besides excluding dirt and dustretains lubricant within the casing and enables the casing to serve as areservoir for lubricant.

Joint member 2 is provided with removable wearing faces 16. Screws 17hold together the parts of member 2. As shown particularly in Fig. 3,the ends of block 1 are spherically curved, so that said block besidessliding in the slideway inmember 2, may also pivot therein from side to.side. Such motion of intermediate member-1, and pivot-al motion of jointmember 3 with referenceA to member 1,. gives the necessary universalmovement. Member 1 being lfree to slide longitudinally with reference tomember 2, the joint combines in a single structure, both a' universaljoint andthe slip joint usually required in connection with universaljoints. Inasmuch as the position of member 1 is not absolutely fixedwith reference to member 2, but may vary somewhat,- casing member 7 maynot be rigidly secured to joint member 3, but must-y be held up againstthe end of member 2 by suitable means. Spring 13 performs lthisfunction.

It will be seen that the casing completely closes the end of theuniversal joint, in all operative positions of the parts thereof.

In Fig. 4 I illustrate alternative means for holding the casing member 7up against the end of joint member 2. In this case la spherically curvedcasing member 18, secured to jacket 5 by a ring 19, and embracing casingmember 7, performs such function. In the construction shown in Fig. 4 Icustomarily provide casing member' 18 with packin material 20. Except asto this casingmem er 18, the joint and casing are substantially the sameas the corresponding parts shown in Figs. 1, 2 and 3.

Figs. 5 and 6 show means for holding the casing member 7 inv position,alternative to that. shown in Fig. 4. In the construction shown in Fig.5, this casing member.l8 has a flange 21 fitting closelyr to the jacket5,

casing member playing between the end of jacket 5 and casing member 18.

In the construction showngin Fig. 6, instead o'f employing a ri'ng l9vofU-section, as in Fig. 4, I employ ay suitable hanged ring 19a. f

. The end member 7 ofthe casing is not necessarily spherically curved,or curved at all. vIn the construction shown in Figs. 7 and 8,saidendmember, 7', is a flat disk playing across the square-cut end of j cket5, and pressed up against said end by s ring 13. In this construction,end member 7 is concentric with jacket 5 only when jointmembers 2 and 3are in line.
